YOUR BUSINESS IS RIDING ON IT.

STEER AXLESLightweight Design

Our front axle I-beam is engineered to handle the

same weight ratings in a more efficient, lightweightdesign. This gives you higher payloads with the same

strength and durability.

Friction and Thrust Bearings

Friction bearings on the left-side steering knuckle

and thrust bearings on the right-side steering

knuckle eliminate chatter and wander, providing

optimal steering feel, tracking and returnability.

The balance of steering resistance and road input

results in significantly better overall steerability.

Needle Bearings

Detroit axles employ needle bearings, which ro

the steering knuckle and king pin. This reducestightens tolerances and reduces deflection to im

durability, reduce tire wear and provide smooth

control. And with better grease distribution, our

axles dont need to be unloaded or lifted to be

Available 12,500-pound Rating

At Detroit, were committed to producing produ

offer optimal real-world solutions for customers

example, our 12,500 lb. axle rating provides an

500 lb. capacity on the front axle, compared to

12,000 lb. rated axle. And you can avoid purcha

heavier, more costly 13,300 lb. axle.

Maximum Maneuverability

The unique I-beam design coupled with an ad

steering layout enables an optimized geometr

sharper wheel cut of up to 55-degrees, giving

tightest turning radius available. Now you can

ETROITAXLES ARE THE RESULT OF AN INTERNATIONAL, CROSS-FUNCTIONAL ENGINEERING

ND PRODUCT DEVELOPMENT EFFORT. OUR PRODUCT LINE IS A PROVEN PLATFORM, FOUND

N MILLIONS OF COMMERCIAL VEHICLES WORLDWIDE. DESIGNED SPECIFICALLY FOR OPTIMAL

ERFORMANCE IN FREIGHTLINER TRUCKS AND WESTERN STAR TRUCKS, DETROIT AXLES

RE MACHINED AND ASSEMBLED IN THE VERY SAME DETROIT, MICHIGAN FACILITY THAT

RODUCES OUR LEGENDARY ENGINES.

ffering steer axle weight ratings from 6,000 to

0,000 pounds, and rear axle weight ratings from

3,000 to 46,000 pounds, Detroit axles cover

very trucking segment from on-highway and

gional delivery to construction and municipal

pplications. A wide range of configuration

ptions and precise compatibility with all braking

ystems offered by Freightliner Trucks and

estern Star Trucks enables you to spec the

xle that is perfect for your exact application.

Engineered, Built and Tested for the Bottom Line

Every Detroit axle provides these money-saving benefits:

Reduced axle weight gives you higher payload, increased fuel

economy and enhanced freight efciency

Lower maintenance costs throughout unit lifecycle for improved

cost of ownership

DRIVE AXLESLarger Differential

Our engineers eliminated the head bearing and

integrated the ring gear in the differential housing to

form one part. As a result they gained additional room

to increase the size of the main differential, giving you

better stability and longer-lasting durability.

recision Cut Gears

he ring and pinion gears are machined using highly-

dvanced dry power cutting and grinding processes

at result in exacting tooth profiles and ideal gear

esh so precise, in fact, that the ring and pinion

ears do not require pairing. These sophisticated

ocesses render perfectly matched gearing to ensureore efficient power transmission, longer durability,

uieter axle operation and enhanced driver comfort.


4/7

REAR AXLEShorough Lubrication

he inter-axle differential gears are completely

bricated even at low speeds using an oil

eflector. The oil deflector is connected to the upper

elical gear that redirects the oil toward the needle

ller bearing and into the carrier, feeding oil to the

put bearing. Standard on all Detroit tandem axles,

e oil deflector eliminates the need for an oil pump in

ost applications to extend gear life, reducing initial

cquisition cost and improving durability.

ypoid and Topoid Gearing

he inter-axle driveline on Detroit tandem rear

xles features a Topoid off-set, in which the

enterline of the pinion is above the centerline of

e ring gear on the second rear axle. This creates

near 0 driveline angle between each axle,

ducing vibration, increasing durability

nd enhancing driver comfort.

Wide-based Single Applications

Detroit innovation helps maximize fuel economy.

Thats why our 40,000 lb. tandem axles are available

with optional 11mm intermediate track housing which

allows the use of super single or dual tires. Up to

34,000 lb. rated capacity, Detroit allows dual or single

tires with the standard housing configuration.

Advanced Input Seal

Unlike competitive units, Detroit drive axles feature

an innovative design for the input seal, which is

inside the bearing cage and separated from the

threaded ring to improve sealing. This significantly

reduces seal degradation and input oil leaks

common to other designs and eliminates the need

for thread sealant on the threaded ring, providing

better reliability and less downtime.

Optional Driver-Controlled Differential Loc

To improve contact with snow or ice-covered r

drivers can actuate the differential lock by flipp

switch on the dashboard. Disengaging the diff

allows the wheels to spin at the same speed, d

the torque to the axle with the most traction, an

you greater confidence under adverse conditio

Optional Automatic Differential Lock

Detroits available NoSpin differential is fully au

It compensates for wheel travel differences whturning under normal conditions by engaging t

differential. On slippery surfaces, it improves tr

without driver input directing power away from

wheel losing traction.
